Biography

My name is Hiram Davis Johnson. There are few things I cherish more than the natural world, and few things I am better at, than sharing my knowledge of nature and its artful order with others. There's nothing more fulfilling than illuminating a difficult topic for someone who has all but given up on it; nothing more enriching than being able to light the spark of fascination with the science of life in others where there was only boredom or frustration before. That said, I hope to be of great use to you all here as a new employee!
